Here we show the laboratory preparation for 10 students working individually, with some excess. Please adjust quantities as needed. 

• To set up for this lab experiment, wear the appropriate personal protective equipment, including a lab coat, chemical splash goggles, and gloves.

• Use a top-loading balance to weigh 50 g of NaCl directly into each bottle. Place the bottles of NaCl at the student workstations.
• Fill enough 250-mL wash bottles with deionized water for each student to have one.
• Set out the following glassware and equipment at each student lab station:
